Microwave irradiation and Click chemistry for highly efficient and chemoselective multivalent iron oxide nanoparticle surface modification

Guénin E., Nehlig E., Demay Drouard P., Benyettou F., Motte L., Université Paris, FR

Magnetic nanoparticles (mNPs) are attractive candidates for numerous applications due to their unique properties. For all these applications mNPs surfaces must be tailored to improve biocompatibility properties or reduce aggregation but also to insert molecules [...]

Removal of Mn (II) from aqueous solution using hematites nanoparticles of different morphologies: Sorption kinetics and equilibrium studies

Iyabodea A.H., Amooa A.F., Siyanbolab F.O., Jabulanib X.B., University of Ilorin, NG

This abstract is submitted to share our own view in the area of synthesis of hematites and their application in the treatment of waste water

Encapsulation of pesticide nanoparticles using polymerized carbon nanotubes and application of synthesized nanocomposite for Alternaria alternata fungi

Sarlak N., Taherifar A., Nejad M.A.F., Zabeti S.M., Salehi F., University of North Carolina at Chapel Hill, US

Polymerization of citric acid onto the surface of oxidized multi wall carbon nanotubes was led to MWCNT-graft-poly (citric acid) (MWCNT-g-PCA) hybrid materials. Trapping of pesticides such as Benomyl, Trichlorfon and Pymetrozine (chess) in aqueous solution [...]

Milling of Nanoparticle Clusters for New Formulation Lubricants

Utomo A.T., Addison T., Konan G., Ozcan-Taskin G., BHR Virtual Pie Ltd., UK

This paper comes from a large project working on the development of novel lubricants, which contain nanoparticles in their formulation, for the automotive industry. Two nanoparticles have been identified to reduce the friction coefficient in [...]

Making Nanoparticles Mega: Scaling-up the Synthesis of Gold Nanoparticle-Wool Fibre Composites

Nilsson T.W., Johnston J.H., Victoria University of Wellington and the MacDiarmid Institute of Advanced Materials, NZ

Gold nanoparticles exhibit intense surface plasmon resonances in the visible region of light. This property allows them to be employed as stable colourants for fine New Zealand wool fibres. A novel proprietary approach for the [...]

Metal-Oxide-Semiconductor Structures with Two and Three-Region Gate Dielectric Containing Silicon Nanocrystals: Structural, Infrared and Electrical Properties

Mateos D., Arias A., Nedev N., Curiel M., Dzhurkov V., Manolov E., Nesheva D., Contreras O., Valdez B., Bineva I., Raymond O., Siqueiros J.M., Autonomous University of Baja California, MX

MOS structures with two and three-region gate dielectrics containing Si nanocrystals are prepared and characterized by TEM, IR spectroscopy and electrical measurements. c Si/SiO2 containing Si NCs/SiO2/Al structures were obtained by high temperature annealing of [...]

Visible Upconversion in Rare-earth Ion-doped NaYF4 Crystals and Nanocoloids

Patel D.N., Jumper M., Wright III D.M., Sarkisov S., Oakwood University, US

Nano-colloids and nano-crystals doped with rare-earth elements have recently attracted a lot of attention in the scientific community. This attention is due to unique physical, chemical and optical properties attributed to nanometer size of the [...]

Synthesis of Magnetically Sensitive Nanomaterials with Tunable Properties

Ieta A., Patus J., Apenowic J., Marius C., State University of New York at Oswego, US

New magnetic nanomaterials with tunable properties were produced using three procedures. (1) Mixtures of polyvinyl alcohol (PVA) solutions and ferric oxide [3] based ferrofluid were prepared and also electrospun with the purpose of synthesizing magnetic [...]

Multi-functional micelles for the combination of chemotherapy and radiotherapy in hepatocellular carcinoma

Shih Y-H, Peng C.L., Luo T-Y, Shieh M.J., National Taiwan University, TW

Hepatocellular carcinoma is the third leading cause of cancer deaths in worldwide. In this study, multi-functional micelles loaded with doxorubicin (Dox) and labeled with the radionuclide rhenium-188 (188Re) were developed to provide the combination of [...]

Highly Spherical Gold Nanoparticles by Laser Pulse Heating

Cavicchi R.E., Meier D.C., Presser C., Guha S., National Institute of Standards and Technology, US

Methods continue to be developed for improving the size and shape uniformity of Au nanoparticles (NP), however, fabricated NPs tend to be faceted and not highly spherical. We present results that show that the faceted [...]
